DRIVING-AXLE STRUCTURE FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application liled March 13, 1205. Serial No. 249.926.

To all whom, it 711/1/ 7/ concern.:

Be it known that I, THOMAS J. LINDSAY, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements Driving-AxleStructures for Automobiles, of which the following is a speciiication.

My invention relates to an improvement in automobile rear-axlestructure, especially of that type shown in my Patent N o. 748,760 ofJanuary 5, 1904.

The object of my present invention is to produce a structure from whichthe compensating gear may be transversely withdrawn without disturbingthe shaft-sections.

The accompanying drawings illustrate my invention as embodied in abevel-gear drive, Figure 1 being a horizontal section of the structurewith the transversely-removable cap omitted 5 Figs. 2 and 3, endelevations of the cooperating ends of a shaft-section and adjacentportion of the compensating gearing; and Fig. 4 a plan, on a reducedscale, of the cap. (Omitted in Fig. 1.)

In the drawings, and 11 indicate a pair of hollow-axle sections whichare connected at their inner ends by means of a gear-inclosing casingconsisting of a portion 12, to which the axle-sections are rigidlyconnected, and a `removable cap 13, which complements the structure 12and which may be readily removed therefrom. Mounted in the axle-sections10 and 11 are shaft-sections 14 and 15, respectively, which in thepresent case are shown as journaled in the axle-sections by suitablebearings B. Journaled in suitable bearingsXis the compensating-gearstructure O, which may be of any desired type, the main gears Gof which,however, preferably permanently project'beyond the bearings X. Theadjacent ends of the gears G and the shaft-sections 14 and 15 areprovided with .coacting parts, which permit transverse withdrawal. Inthe present case said connections consist of a diametrical slot 16,formed across the end of the shank of the gear G, and a correspondingdiametrical rib 17, formed at the end of the shaft-section 14 or 15. f

The bearings X are preferably bodily transversely removable from thecasing 12.

In operation the shaft-sections 14 and 15 may remain in position', andwhen the cap 13 is removed and the shaft-sections turned until theportions 17 of the two shaft-sections lie at substantially right anglesto the casing 12 the compensating-'gear structure C may be bodilytransversely withdrawn from the structure without disturbing theshaft-sections in the axle structure.

I claim as my invention` 1. In a driving-axle structure for automobiles,the combination of a hollow-axle structure, a pair of shaft-sectionsmounted therein and having their adjacent ends separated, acompensating-gear structure journaled in the axle structure between theadjacent ends of the' shaft-sections, and driving connections betweenthe said shaft-sections and compensating gear permitting transversewithdrawal of the compensating gear without axial movement of theshaft-sections.

2. Ina driving-axle structure for automobiles, the combination of ahollow-axle structure, a pair of shaft-sections rotatably mountedtherein with their adjacent ends separated, a rotatable driving elementmounted in said structure between the adjacent ends oftheshaft-sections, and driving connections between said rotatabledriving element and the adjacent ends of the shaft-sections permittingtransverse withdrawal of the driving element without axial movement ofthe shaft-sections.

3. In a driving-axle structure for automobiles, the combination of, ahollow-axle structure consisting of a pair of hollow casings, and anintermediate larger casing connecting the adjacent ends thereof andconsisting of a main portion and a removable cap, a pair ofshaft-sections mounted in said axle structure and having their adjacentends sepaings and an intermediate larger casing connecting the adjacentends thereof and consisting of a main portion and a removable cap, apair of shaft-sections mounted in said axle rated but projecting intothe intermediate cas- A IOO ture consisting of a pair of hollow axlecasstructure and having their adjacent ends separated but projectinginto the intermediate casing, a compensating-gear structureindependently journaled in the main portion of said larger casing, anddriving connections between said compensating-gear structure and theadjacent ends of the shaft-sections permitting transverse withdrawal ofthe compensating-gear structure without axial movement of theshaft-sections.

5. In a driving-axle structure for automobiles, the combination of, ahollow-axle structure, a pair of shaft-sections mounted therein andhaving their adjacent ends separated, a compensating-gear structurejournaled in the axle structure between the adjacent ends of theshaft-sections, and a driving connection between the inner end of eachshaft-section and the adjacent portion of the compensating gearconsisting of a diametrical rib and corresponding slot permittingtransverse withdrawal of the compensating gear without axial movement ofthe shaft-sections.

6. In a driving-axle structure for automobiles, the combination of, ahollow-axle structure, a pair of shaft-sections rotatably mountedtherein with their adjacent ends separated, a rotatable driving elementmounted in said structure between the adjacent ends of the'shaft-sections, and a driving connection between each end of therotatable driving element, and the adjacent shaft-section end consistingof a diametrical rib and slot permitting transverse withdrawal of thedriving element without axial movement of the shaftsections.

7. In a driving-axle structure for automobiles, the combination of, ahollow-axle structure consisting of a pair of hollow casings, anintermediate larger casing connecting the adjacent ends thereof andconsisting of a main portion and a removable cap, a pair ofshaftsections mounted in said axle structure and having their adjacentends separatedl but projecting into the intermediate casing, acompensating-gear structure arranged in said larger casing between theadjacent ends of the shaft-sections, and a driving connection betweeneach end of said compensating-gear structure and the adjacentshaft-section end consisting of a diametrical rib and slot permittingtransverse withdrawal of the compensating-gear structure without axialmovement of the shaft-sections.

S.. In a driving-axle structure for automobiles, the combination of, ahollow-axle structure consisting of a pair of hollow-axle casings and anintermediate larger casing connecting the adjacent ends thereof andconsisting of' a main portion and a removable cap, a pair ofshaft-sections mounted in said axle structure and having their adjacentends separated but projecting into the intermediate casing, acompensating-gear structure independently journaled in the main portionof the larger casing, and a driving connection between each end of saidcompensating-gear structure and the adjacent shaftsection end consistingof a diametrical rib and slot permitting transverse withdrawal of thecompensating gear structure without axial movement of theshaft-sections.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 3d day of March, A. D. 1905.
